Tsukidate no Satsujin

After the death of her parents, high school student Sorami Karigaya boards the night train Genya to meet her estranged grandfather, her only remaining relative. Her journey is filled with firsts: her first train ride, her first time seeing snow, and her first visit to Hokkaido. Awaiting her on board, however, is a group of eccentric and obsessive railway enthusiasts, known as "Tetsu". The luxurious Genya train, which utilizes former Orient Express carriages pulled by the D51 steam locomotive, contains only seven passengers. Sorami soon discovers her grandfather personally invited all of them. This peculiar gathering takes a sinister turn when a passenger is found murdered aboard the moving train, abruptly dragging Sorami into a brutal and terrifying mystery.
